Most people buying a used car will kick the tyres, check the bodywork for dents, and maybe take it for a quick spin around the block. What a lot of people don’t do is ask for the service history — and that’s usually where the real story of a car lives.
So What Is It?
Every time a car goes in for a service, the garage logs what they did, what parts they replaced, when it was done, and how many miles were on the clock. That record, whether it’s in a little stamped booklet or printed off from a computer, is the service history. Think of it like a medical record for your car.
Buying a Used Car Without One Is a Gamble
Here’s the thing — a car can look absolutely fine on the outside and be a complete nightmare underneath. Regular servicing catches small problems before they turn into big expensive ones. If a car has no service history, you’ve got no way of knowing whether the oil’s ever been changed, whether the cambelt’s been done, or whether the previous owner just crossed their fingers and hoped for the best.
A full service history doesn’t guarantee a car is perfect, but it does tell you someone actually bothered to look after it. That counts for a lot.
It Affects the Price Too
Sellers with a full service history can and should ask for more money. Buyers know what they’re getting, there’s less room for doubt, and the whole negotiation tends to be a lot less painful. On the flip side, if you’re buying a car with no history or a patchy one, use it to negotiate the price down. The uncertainty is a genuine risk and the price should reflect that.
Where Do You Find It If It’s Missing?
If you’ve lost your own service book, start by calling the last garage that worked on the car. Most places keep records on their system going back years. If the car has been serviced at a main dealer, the manufacturer might have records too — worth a phone call.
Most cars from 2012 onwards have an online service history. You can check it instantly by entering your registration number, and the report will pull up all the recorded services for that car, including records directly from the manufacturer and garages that use the online service database.
For older cars it gets trickier. Records get lost, garages close down, owners forget. Sometimes the history just isn’t there and you have to make a judgement call based on everything else.
Full History vs Part History
Full service history means every service is accounted for, right back to when the car was new. Part service history means some of it is there but not all of it. Neither is necessarily a red flag on its own, but full is always better and worth paying a bit more for.
Can You Trust the Stamps in the Book?
Mostly yes, but not always. Service book stamps can be faked — it’s not common but it happens. If something feels off, ring the garages listed and ask them to confirm the work was done. Takes five minutes and could save you a lot of bother.
It’s also worth running a vehicle history check alongside any service records. The check won’t show you what oil was used or when the brakes were last done, but it will tell you if the mileage looks dodgy, if there’s finance still owed on the car, or if it’s ever been written off and repaired. Put that together with a genuine service history and you’ve got a pretty solid picture of what you’re actually buying.
How Often Should a Car Be Serviced?
Once a year or every 12,000 miles is the standard rule, whichever comes first. Check the owner’s manual for your specific car as some need more frequent attention. If you mainly do short trips around town, it can actually be worth servicing more regularly even if the mileage is low — short journeys are surprisingly hard on an engine.
Keep Your Own Records
If you own a car, keep everything. Every receipt, every invoice, every piece of paper a garage hands you — put it somewhere safe. It costs you nothing and adds real value when it comes to selling. Buyers notice when a seller has looked after their paperwork. It tells them something about how the car itself has been looked after too.
